SCRAPER ATTACHMENT FOR ICE-PLANERS.

SPECIFICATION forming part of Letters Patent No. 354,361, dated December14,1886.

Application filed Apr-H15, 1856. Serial No. 198,931. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM J. TEMPLE, a citizen of the UnitedStates,residing at Hamp den, in the county of Penobscot and State of Maine,have invented a new and useful ScraperAttachment for Ice-Planers; and Ido hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to an improvement in icelaners,consisting of ascraper attachment thereto, and isillustrated in the accompanyingdrawings, in which- Figure 1 is a plan of an ice-planer with my scraperattachment. Fig. 2 isan elevation of the same. Fig. 3 is an end View,showing method of pivoting scraper attachment in jaw of bolt.

Similar letters refer to corresponding parts throughout the figures.

Hitherto ice-planers have been used without scraper attachments, and asthey are usually operated with a pair of horses, the footing of onehorse of the pair is constantly upon the loose snow and ice shavingsthrown up over the planing-tool in the previous passage of the planer.One of the pair then walking upon a firm footing and the other upon aloose and uncertain footing, the work of the two horses is very unequal,and the full strength of both cannot be utilized. It is to remedy thisdifficulty that I have invented my device, which may easily be attachedto the common rectangular frames of the planers now in use.

My improvement consists in the addition of a scraping-tool somewhatsimilar to those used in road-machines, and in the manner of attachingand operating the same.

To the side pieces, a a, of the rectangular frame of the planer, 0rto-upward projections therefrom, and behind the planing-tool B, I pivot,as at x x, a hanger or support, 0, bent to a bow or angle at 0, so thatthe bow c of the hanger shall projectbehind the side pieces, a a, of theframe and be adjustable at any de sired elevation within convenientlimits. I further provide means of locking the hanger when adjusted atthe desired elevation. This may be accomplished in various ways. Thatwhich I have adopted is to prolong the extremities of the hanger belowthe points where they are pivoted to the frame, turning them downward ata considerable angle from that point and forming in them slightly-curvedslots 0 0, through which they are bolted to the side pieces, a a, andsecured by nuts 0 at any desired point in the length of said slot-s, theexact point being determined by the amount of elevation to be given tothe hanger.

Various forms of hangers may doubtless be devised, the essential pointsbeing that the hanger shall project behind the frame to afforda point ofsuspension for the, scrapingtool hereinafter described, and shall becapable of being adjusted at different elevations.

I also provide a scraping-tool, D, preferably rectangular in shape. Itis pivoted at d edgewise, to allow either end to tilt upward ordownward,and preferablyoff the middle of its length in a slot or jaw, d,in the lower extremity of a round bolt, d. The upper extremity of thebolt d passes through a bolthole in the bow c of the. hanger O, and issecured on the upper side thereof, preferably detachably, by anut orkey, 61'. The scraper D is thus suspended from the hanger G, and whenpivoted off the middle of its length is so adjusted that its longer endmay swing within the sidepieces, a a, of the frame.

To the inner end of the scraper D is pivoted the rigid rod E,prcferablyof such length that when the scraper is swung diagonally to theplaningtool and its inner end bears upon the inner side of one of theside pieces, a a, of the frame, the other end of the rod may be securedrigidly and detachably to some convenient point upon the machine,preferably within the reach of the driver. I have shown it bent overintoa hook and resting in a staple, e, fixed in the back of the drivers seatF.

In operation the hanger O, pivoted at x x, is turned and set at anydesired elevation and locked there, as before described. Thescraper D isswung with its pivot (1 until its inner end bears upon the inner side ofeither one of the side pieces, a c, of the frame, as required, and therod E hooked to the staple c, and the scraper is thus locked inthat-position and prevented from swinging. The machine being started andthe planing commenced, the planings rise and fall over behind theplaning-tool B in front of the scraper D, by which they are caught andshunted off to either side, accordingly as the scraper is adjusted,which, in practice,is always upon the course last previously scraped,and the course thus planed and scraped is left clean,so that the horsetraveling thereon atthe neXt course has a clean, hard, and smoothfooting, and is enabled to pull equally with his mate. Ifind,practically, that when my scraper is used the same pair of horsescan do much more work in a given time than without it, and that lighthorses can perform the work for which heavy teams are usuallyrequired,an d that a material saving is thus accomplished. When onecourse is completed and the planer is turned round to plane back to thestarting-point, the rod E is disengaged from its attachment to the seator frame and the scraper swung round, so that its inner end rests andbears upon the opposite side of the frame and the rod hooked to itspoint of support, as before, and this may be done without the driversleaving his seat.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. A scraper attachment for ice-planers, consisting of a scraping-toolpivoted at or near the middle of its length to a vertically-adjustablehanger projecting behind the frame of the planer in such a manner thatone end of said scraper may swing within the side pieces of said frame,and bear upon one of said pieces when the machine is in operation,substantially as described.

2. A scraper attachment for ice-planers, consisting of the combinationof a hanger projecting behind the frame of the planer, and verticallyadjustable at various elevations thereon, a scraper pivotally suspendedat or near its mid-length from said hanger, in such a manner that oneend of said scraper may swing within the side pieces of said frame, andbear upon one of said side pieces when said scraper rests diagonally tothe planing-tool, and a rigid rod pivoted at one end to the inner end ofsaid scraper, and detachably securable at the other end to someconvenient point of said frame, substantially as described.

3. A scraper attachment for ice-planers, consisting of the combinationof a hanger projecting behind the frame of the planer, and vcr ticallyadj ustable at various elevations thereon, a scraper pivotally suspendedat or near its mid-length from said hanger, in such a manner that eitherend of said scraper may tilt upward or downward and that one end of saidscraper may swing within the side pieces of said frame, and bear uponone of said side pieces when said scraper restsdiagonally to theplaning-tool, and a rigid rod pivoted at one end to the inner end ofsaid scraper, and detachably securable at the other end to someconvenient point of said frame, substantially as described.

4. In combination with an ice-planer and its frame, the herein-describedscraper attachment, consisting of the combination of the hanger O,pivoted to the side pieces, a a, of said frame, and having bow or angle0 and slots 0 0, bolts and nuts at c c, scraper D, suspended from saidhanger in such a manner as toswing both vertically and horizontally, andrigid rod E, pivoted at one end to the inner end of said scraper, anddetachably seci'irable at the other end to some part'of the frame orseat of said planer, substantially as described.
